On this day (11 July) in 1804, an early-morning duel between Aaron Burr and Alexander Hamilton took place. To commemorate this fateful moment in North American history, I am posting below some historic odds and ends: a YouTube video showcasing the actual pistols used in the duel; a TikTok video featuring Hamilton Park in Weehawken, N.J., where this famous duel took place; and the song “Ten Duel Commandments”. P.S.: The last duel to take place in Argentina occurred in 1968! (See here and here; second link in Spanish.)
